Perhaps U.S. should scan packages before delivery
In an effort to keep our skies safe, several years ago we implemented a rule that every suitcase and computer that went on a plane had to be scanned for dangerous items and unsafe contents. Everyone is scanned, no matter what race, creed or color you are.
We are living in unsafe times and since our country is a melting pot, which adds to a rich and diverse country, why not scan items that come through mail-order delivery, like the Postal Service, FedEx and UPS. It may be a huge effort to accomplish, but packages that repeatedly come to the same address filled with such items as contents to build bombs could be monitored and followed up on, possibly averting tragedy.
